LUBRICATING- DEVICE FOR JOURNAL-BOXES.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed April 20, 1908. Serial No. 428,001.

To all 'whom it may concern:

Be it known that I, JAMES G. SMITH, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Lubricating Devices for J ournal-Boxes of which the following is a specification.

My invention relates to a lubricating journal box for car and locomotive journal boxes, and the like.

The object of the invention is to provide a simple and convenient way of forming a cellar, a tray and the dust guards, and oonnecting them to one another and to the main bearing support.

The features of my invention will be more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation, partly in section. Fig. 2 is a section on line x, x, Fig. 1. Fig. 3 is a top plan view showing the dust guard, cellar and tray. Fig. 4 is a perspective view of the lubricating tray. Fig. 5 is a section on line w, w, Fig. 1. Fig. 6 is an enlargedsection through one corner of the cellar, shown in Fig. 5.

1 represents the main bearing support. 2 the brass or top bearing for the axle 3.

4 represents the cellar of the lubricating device which slips into a receptacle formed on the under side of the main bearing sup.

port 1, it being held in placeby means of the eye lugs 5, 6, and the bolt 7, as shown in Fig. 2.

8 represents the tray which carries the lubricating packing forming the under bearing for the axle. It is of box-like formation, the two sides being rovided with the inwardly extending poc ets 9 open at the bottom and on vthe outside. In the corners of the cellar are pin pockets 10, in which are mounted coil springs 11, pressing the tray normally upward from the cellar. The ends of the tray are provided with the inwardly extended guide recesses 12.

13 represents the dust guards at opposite ends oi the cellar and separating the cellar -from the ends of the lubricating tray. These dust guards are provided with hollow guide osts 14, which rit within the guide recesses 12 of the lubricating tray.

15 re resents springs seated on the floor oi the cel ar in pin pockets and fitting within the hollow posts 14 and pressing the dust guards normally upward. from the cellar. Thus the lubricating tray and the dust guards are independently spring supported. on the loor of the cellar. T he dust guards are snugly iitted in the ends of the cellar and the interlocking guide formed by the engagement of the posts 14, into the recesses 12, holds the guards and the tray in mutual alinement and position with one another and with the cellar, insuring their perfectly even and uniform vertical movement.

These parts are very efhcient in operation, easy of access and easily renewable.

Having described my invention, I claim 1. In a lubricating device for car and locomotive journal boxes, a cellar detachably secured to the main bearing support, a

lubricating bearing tray having pin pockets, l

springs in said pockets seating upon the floor of the cellar, dust guards having projected hollow posts, springs in said posts bearing on. the floor of the cellar, and guide recesses formed in the tray with which the said hollow posts of the dust guards engage, substantially as described.

2. In a lubricating device for car and locomotive journal boxes, a cellar, a tray and dust guards having interengaging guide devices and independent springs on the floor oi the cellar for said guards and tray, substantially as described.

In testimony whereof, I have hereunto set my ha nd.
